TE Connectivity 104656-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104656-5 is a surface mount rectangular connector header with 50 positions arranged in 2 rows at 0.050" (1.27mm) pitch. This connector is part of the AMPMODU 50/50 Grid series and features shrouded 4-wall construction with push-pull fastening. The part is currently active in production with 908 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing direct functional replacement in board-to-board applications. Substitution becomes necessary due to inventory availability, compliance requirements, or design optimization needs.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the 104656-5:

Direct Equivalent (Identical Parameters): The part 5-104656-5 maintains all critical electrical and mechanical parameters of the main part, including pitch (0.050"), position count (50), row configuration (2 rows), mounting type (surface mount), shrouding (4-wall), fastening (push-pull), and operating temperature range (-65°C ~ 105°C). The primary distinction is RoHS compliance status and contact finish post material (Tin versus Tin-Lead).

Similar Equivalents (Compatible Parameters with Variations): Parts from Samtec Inc. (TFM-125 series) and Harwin Inc. (G125-MS15005L3P) maintain core mechanical compatibility through identical pitch (0.050" or 0.049"), position count (50), row configuration (2 rows), mounting type (surface mount), shrouding (4-wall), and termination (solder). These parts differ in contact shape (square versus circular), current rating capacity, operating temperature range, and fastening mechanism, which may affect application suitability.

Key Parameters for Substitution Determination:

Engineering Selection Recommendations

Direct Equivalent Selection: The part 5-104656-5 is the primary direct equivalent to 104656-5. Both parts maintain identical electrical and mechanical specifications, including pitch, position count, row configuration, operating temperature range, and current rating. The 5-104656-5 offers improved compliance status with RoHS Compliant certification, whereas the main part is RoHS non-compliant. Selection of 5-104656-5 is appropriate for applications requiring RoHS compliance or when inventory of the main part is depleted.

Samtec Tiger Eye™ TFM Series Selection: The TFM-125-12-L-D, TFM-125-12-S-D-LC, and TFM-125-12-SM-D-LC parts from Samtec maintain mechanical compatibility through identical pitch (0.050"), position count (50), row configuration (2 rows), and shrouding (4-wall). These parts feature enhanced current rating capacity (2.9A per Contact versus 0.5A), extended operating temperature range (-55°C ~ 125°C), and ROHS3 compliance. The TFM-125-12-S-D-LC and TFM-125-12-SM-D-LC variants include Board Lock features. Selection of Samtec parts is appropriate for applications requiring higher current capacity or extended temperature performance within the -55°C ~ 125°C range.

Harwin Gecko Series Selection: The G125-MS15005L3P from Harwin Inc. maintains mechanical compatibility through identical position count (50), row configuration (2 rows), and shrouding (4-wall). The pitch specification is 0.049" (1.25mm), which differs marginally from the 0.050" (1.27mm) standard. This part features enhanced current rating (2A per Contact), extended operating temperature range (-65°C ~ 150°C), and ROHS3 compliance. The fastening mechanism is Latch Lock rather than Push-Pull. Selection of the G125-MS15005L3P is appropriate for applications requiring extended temperature performance to 150°C or when Latch Lock fastening is preferred.

Compliance Considerations: All substitute parts carry active product status. The 5-104656-5 is RoHS Compliant, while Samtec and Harwin parts are ROHS3 Compliant. Applications subject to RoHS directives should select compliant alternatives. The main part 104656-5 is RoHS non-compliant and REACH Affected; substitute parts offer improved regulatory alignment.
